[Intracranial lipomas--report of six cases].

Intracranial lipoma is a very rare tumor, and infantile lipoma has been reported quite scarcely. The authors recently have encountered six cases of intracranial lipoma, five are infants and one is adult, on which the results of neuroradiological examinations, especially CT findings are reported. Two of six cases had lipoma of the corpus callosum associated with cranium bifidum at the midline of frontal region. Two of six cases had lipoma occurred at the quadrigeminal cistern. To one of them showing advanced enlargement in circumference of the head in the postnatal period, the V-P shunt was conducted for obstructive hydrocephalus. Another case had agenesis of the corpus callosum associated with interhemispheric cyst. One case out of six had lipoma originating from the left sylvian fissure and the remaining adult patient had lipoma located in the interpeduncular cistern. Four cases out of those six were associated with agenesis of the corpus callosum. Based on published reports, the etiology, neuroradiological features, clinical symptoms and signs, differential diagnosis and surgical indication were discussed.

[A case of arterio-venous malformation associated with agenesis of unilateral internal carotid artery (author's transl)].

A case of arterio-venous malformation (AVM) at the right parietal area in association with agenesis of the left internal carotid artery (ICA) is described. A 27-year-old male complained of severe headache and vomiting on September 27th in 1980. He lost his consciousness and became stuporous within several minutes after the ictus. He was then transferred to Kurume University Hospital. On admission, he was semicomatose, anisocoria and left hemiparesis marked in the lower limbs, and bilateral Babinski reflex were noted. A emergency CT scan revealed a round high density area suggesting intracerebral hematoma at the right parieto-occipital area. Right retrograde brachial angiography was then performed which showed a small AVM at the right parietal lobe mainly fed by the right posterior parietal arterial branch, and drained into the superior sagittal sinus, via the subcortial veins. Left MCA bilateral PCA and SCA also were demonstrated on the angiogram. The angiogram suggested on abnormality of the Willis ring. Emergency operation fro the small AVM associated with intracerebral hematoma was then performed. The AVM was sufficiently removed and approximately 80 gr. of intracerebral clots were also evacuated completely. Histological examination indicated a typical small AVM. The postoperative course was uneventful. Left CAG performed by seldinger method from the femoral artery after the operation showed no demonstration of the left ICA. the left common carotid artery was terminated as the external carotid artery without carotid bifurcation at the neck. The left ophthalmic artery was fed by the meningeal artery of the internal maxillary artery. Left vertebrobasilar system was normal. From an angiogram, the agenesis of the left ICA was most suspected. An agenesis of ICA was uncommon among the literature in which there was no case with this anomaly associated with cerebral AVM. The embryological consideration about this case was mainly discussed.

[Two cases of craniolacunia associated with meningocele and meningoencephalocele (author's transl)-a1].

Craniolacunia (lacunar skull, Luckenschadel) is characterized by multiple, round or oval, radiolucent defects, sharply separated by dense strip of bone (honey comb like configuration) which tend to cluster in the cranial vault on plain skull film. Craniolacunia is present at birth and frequently associated with myelomeningocele, encephalocele or other congenital abnormalities of the central nervous system. Patients with carniolacunia have high mortality due to these associated lesions, and to the secondary effects of these neurological lesions. Recently, it is interested that the presence of carniolacunia can be used as an early indicator of intellectual capacity or recommendation of early indicator of intellectual capacity or recommendation of early surgery for associated lesions. Two cases of craniolacunia with meningocele in the lumbar region and encephalocele in the frontal region are presented and the etiology, clinical significance, prognosis of craniolacunia are discussed. Case 1 (Fig. 1, 2, 3), who had a soft tumor in the lumbar region since birth, was admitted to Saiseikai Yahata Hospital under the diagnosis of meningocele on October 26, 1973. The circumference of the head was 32.5 cm, and the lumbar tumor was infant fist growth, oval, brownish and soft in appearance. The patient had no neurological positive signs or other abnormalities including chest, abdomen and extremities. Plain skull film showed typical craniolacunia in the parietal, frontal and occipital region of the vault. Three days after admission, the patient had opisthotonus like posture at times and convulsive seizure of extremities. Suspected of meningitis, ventricle tap was performed. From the findings of obtained cloud xanthchromic cerebrospinal fluid which was revealed pleocytosis and many Klebsiella or other Gram (-) bacilli on bacterial culture, the diagnosis of ventriculitis was made...
